PA11 PA12 Made from castor beans (!!!) Nylon like Polyamides. Inferior in many ways to Nylon 6 and Nylon66 BUT good water related performance - low absorption. Also maintain propertis well with time. Hydraulic brake hoses.

Derived from a series of complex chemical operations, RILSAN PA 11 is one of the few polymers in existence produced from a =91green=92raw material =97 castor beans. RILSAN PA resins have earned a preferred material status in the most demanding applications due largely to their unique combination of thermal, physical, chemical and mechanical properties. This results in an outstanding Cost Performance Ratio. Processing ease is another major benefit of RILSAN polyamide resins. Supplied in powder or pellet form RILSAN PA resins can be processed by injection molding, extrusion, blown film extrusion, extrusion blow molding or rotomolding. RILSAN PA 11 and 12 are available in rigid, semi-flexible and flexible grades. Reinforced and conductive grades are also produced. RILSAN polyamide resins have a unique combination of properties. Their ease of processing has led designers to select them for industries as diverse as offshore drilling, electrical cables, automotive, and pneumatic and hydraulic hose. The most demanding applications require RILSAN polyamide resins.
